I agree that if you really value stereo music, you can't use the same gear for video.
Get speakers that suit both purposes and then set up your audio system however you like.
Then add either an AV receiver, or do what I do (but it is far more expensive) and add a really good AV pre and separate power amp - in other words two completely different amplification paths, one for music and one for video. Just takes a minute to pull the speaker wires from one and plug them into the other - using good quality banana plugs speeds it up over having to undo spades or bare wires.
